The clean output of the TR-909 has been recorded to a CrO2 audio cassette, adding a layer of noise and grit to the sound. The processed samples were recorded to an audio cassette at two different gain settings, resulting in two separate kits with a different lo-fi flavor.

The library features 155 drum samples in 24-bit WAV format. All included samples are normalised to -0.1 dB and edited carefully to avoid any pops and clicks. The included sounds are 100% royalty free.
